Working Principle

The CMX309HWC49.152M-UT Oscillator works by utilizing the principles of quartz crystal resonators. Quartz crystals are piezoelectric materials that change shape when an electric field is applied to them. When a voltage is applied to the quartz crystal of an oscillator, it takes a certain amount of time for the crystal to resonate at its desired frequency. As the voltage is increased, the crystal begins to vibrate, generating an electrical signal. The electrical signal is then amplified and filtered by the oscillator circuit, resulting in a periodic signal of the desired frequency.

The CMX309HWC49.152M-UT Oscillator has a built-in oscillator circuit which monitors the crystal frequency and can adjust the amplitude of the output wave so that it resonates at a specific frequency. This adjustment is referred to as frequency compensation, and it ensures that the oscillator is operating at the desired frequency. By utilizing this principle, the oscillator can maintain a stable and repeatable performance over an extended period of time.
